ACTITUD HACIA EL CAMBIO DE USO DE SUELO EN LA REGIÓN GOLFO CENTRO DE VERACRUZ, MÉXICO

El objetivo de esta investigación fue conocer la actitud de los productores del mango y caña de azúcar hacia el cambio de uso de suelo, en la región Golfo centro de Veracruz, México. La metodología fue propuesta para analizar la actitud con la técnica de Likert, combinando aspectos sociales y agro-ecológicos, a través de enunciados sociales, ambientales y económicos. Los productores (n=90) de siete ejidos se estratificaron en tres grupos: mango, caña reciente y caña persistente. Los resultados demuestran actitud positiva alta (3.95) hacia el cambio de uso del suelo, significativamente mayor (ANDEVA F=3.69; p=0.03) para los productores de caña reciente comparados con los productores del mango (3.79). En contraste, los productores de caña persistente presentaron actitud similar (3.85) comparada con los productores de mango. Usando el análisis multivariado basado en las dimensiones sociales, ambientales, económicas y autoevaluación prospectiva - retrospectiva, se identificaron tres grupos: rechazo-rechazo, aceptación-rechazo y aceptación-aceptación

Post-Franco Theatre

In the multiple realms and layers that comprise the contemporary Spanish theatrical landscape, “crisis” would seem to be the word that most often lingers in the air, as though it were a common mantra, ready to roll off the tongue of so many theatre professionals with such enormous ease, and even enthusiasm, that one is prompted to wonder whether it might indeed be a miracle that the contemporary technological revolution – coupled with perpetual quandaries concerning public and private funding for the arts – had not by now brought an end to the evolution of the oldest of live arts, or, at the very least, an end to drama as we know it

Non-additive effects of RBP4, ESR1 and IGF2 polymorphisms on litter size at different parities in a Chinese-European porcine line

BACKGROUND: The aim of this work was to study the effects on litter size of variants of the porcine genes RBP4, ESR1 and IGF2, currently used in genetic tests for different purposes. Moreover, we investigated a possible effect of the interaction between RBP4-MspI and ESR1-PvuII polymorphisms. The IGF2-intron3-G3072A polymorphism is actually used to select lean growth, but other possible effects of this polymorphism on reproductive traits need to be evaluated. METHODS: Detection of polymorphisms in the genomic and cDNA sequences of RBP4 gene was carried out. RBP4-MspI and IGF2-intron3-G3072A were genotyped in a hyperprolific Chinese-European line (Tai-Zumu) and three new RBP4 polymorphisms were genotyped in different pig breeds. A bivariate animal model was implemented in association analyses considering the number of piglets born alive at early (NBA(12)) and later parities (NBA(3+ )) as different traits. A joint analysis of RBP4-MspI and ESR1-PvuII was performed to test their possible interaction. In the IGF2 analysis, paternal or maternal imprinting effects were also considered. RESULTS: Four different RBP4 haplotypes were detected (TGAC, GGAG, GAAG and GATG) in different pig breeds and wild boars. A significant interaction effect between RBP4-MspI and ESR1-PvuII polymorphisms of 0.61 ± 0.29 piglets was detected on NBA(3+). The IGF2 analysis revealed a significant increase on NBA(3+ )of 0.74 ± 0.37 piglets for the paternally inherited allele A. CONCLUSIONS: All the analyzed pig and wild boar populations shared one of the four detected RBP4 haplotypes. This suggests an ancestral origin of the quoted haplotype. The joint use of RBP4-MspI and ESR1-PvuII polymorphisms could be implemented to select for higher prolificacy in the Tai-Zumu line. In this population, the paternal allele IGF2-intron3-3072A increased litter size from the third parity. The non-additive effects on litter size reported here should be tested before implementation in other pig breeding schemes

Benito Pérez Galdós

In Galdós\u27 time, the tensions between such diverse phenomena as coins and credit, free trade and protectionist tariffs, factory work and domestic economy, masculine and feminine, and private and public exacerbated friction among peoples—those of pueblo and rural origins, whose voices rasped and whose bright colors raked the eye, and a nascent, insecure bourgeosie who, fearful of the masses, strove to imitate the aristocracy. Old and new converged also with the question of suffrage and citizenship to aggravate social malaise and political upheavals—Carlist wars, palace intrigues, the Revolution of 1868 and overthrow of Queen Isabel, the brief reign of Amadeo of Savoy, the aborted First Republic and the Bourbon Restoration (1875-1885), which reached Spain from England in the imported person of Alfonso XII. These turbulent events undergird the cultural, historical, and political events of the novels by Benito Pérez Galdós (1843–1920) to be discussed in this chapter. Galdós is the author of seventy-seven novels, twenty-six original plays, and numerous occasional pieces, written between 1867 and 1920. These divide into two main categories: the historical and the contemporary social novels, now more appropriately described as novels of modernity The forty-six historical novels, called Episodios nacionales, make up five series, each consisting of ten interconnected novels, except the fifth series, left unfinished. The thirty-one novels of modernity, published between 1870 and 1915, also divide into two groups: Novelas de la primera época ( Novels of the Early Period, 1870–1879) and Las novelas de la serie contemporánea ( The Contemporary Social Novels, 1881–1915). The novels of the early period comprise Galdós\u27 first attempts at novel writing, as well as four so-called thesis novels : Doña Perfecta (1876), the sequel Gloria (1876–1877), Marianela (1878), and La familia de León Roch ( The Family of León Roch, 1878–1879). The next group of novels represents what Galdós called his segunda manera —his second style, a different kind of writing ... a more sophisticated and varied mode of narrative presentation
